Add a File

Add a PPTX file named document.pptx to your project folder. You can also use our sample file. The file name is case sensitive. Make sure the file name matches the file name in the sample code.

Run the Code

Copy the code and run it from the same folder you added the files to. For more information, see our language-specific getting started guides.

Your API Key

Rendering a Single Page

The default is to render the first page, but you can also render any other page of the document by adding the pages option.

This will render the fifth page (remember pages are indexed starting from 0):

"output": {
  "type": "image",
  "pages": {"start": 4, "end": 4},
  "format": "tiff",
  "width": 500
}

Rendering Multiple Pages

In addition to rendering just a single page (the default is the first), you can also render multiple pages at the same time. Simply add the pages option.

Note: You can only render 50 pages in a single request. Requesting more than 50 pages will result in a status 400 being returned.

The following example will return a ZIP file containing all pages:

"output": {
  "type": "image",
  "pages": {"start": 0, "end": -1},
  "format": "tiff",
  "width": 500
}

You can also render a subset of pages. This will render pages 2, 3, and 4:

"output": {
  "type": "image",
  "pages": {"start": 1, "end": 3},
  "format": "tiff",
  "width": 500
}

The files in the ZIP file will be named <page_number>.tiff

Controlling Image Dimensions

You can give the output images a specific width or height, or you can render them with a specific resolution. You can only choose one of those three options. Specifying more than one will result in a status 400 being returned.

Depending on which option you choose, one or both dimensions will be determined based on the dimensions of the page in the document. The following will go into detail about each of the three options.

Note: There is a limit to the final resolution of the resulting images. Any image is not allowed to be bigger than 34 million pixels (4960×7016px), regardless of the aspect ratio. Requesting a bigger image will result in a status 400 being returned.

You can specify the width . In this case, all rendered pages will have the same width, but they’ll have varying heights depending on the page dimensions in the document:

"output": {
  "type": "image",
  "format": "tiff",
  "width": 768
}

You can specify the height . In this case, all rendered pages will have the same height, but they’ll have varying widths depending on the page dimensions in the document:

"output": {
  "type": "image",
  "format": "tiff",
  "height": 1024
}

And finally, you can specify the dpi . In this case, the width and height of the rendered pages depends only on the page dimensions:

"output": {
  "type": "image",
  "format": "tiff",
  "dpi": 72
}

Security is our top priority

No document storage

No input or resulting documents are stored on our infrastructure. All files are deleted as soon as a request finishes. Alternatively, check out our self-hosted product.

HTTPS encryption

All communication between your application and Nutrient is done via HTTPS to ensure your data is encrypted when it’s sent to us.

Safe payment processing

All payments are handled by Paddle. Nutrient DWS Processor API never has direct access to any of your payment data.
